Answer:

The maturation of leukocytes arise from hemopoietic stem cells in the bone narrow. They are involved in pathogen recognition.

The main function of mature leukocytes is to defend the body against diseases.

Explanation:

Pathogen is any organism or substance, specially a microorganism capable of causing diseases. For example: virus, bacteria, protozoa or fungi. The microorganism will only be considered pathogenic when its population has grown enough to cause a disease.

The leukocytes are a major component of the body's defenses.

They have a nucleus, are capable of motility and defend the body against infections and diseases by ingesting foreign materials and cellular debris, by destroiying infectious agents and cancer cells, or by producing antibodies.

A healthy adult human has between 4.500 and 11.000 white blood cells per cubic millimetre of blood. Variations on the amount can occur during the day.

An abnormal increase in white cell number is known as leukocytosis, whereas an abnormal decrease in number is known as leukopenia.

The count may decrease in response to certain types of infections or drugs or in association with certain conditions, such as chronic diseases like anemia and anaphylaxis.

Answer:

The leukocytes are the main defenses of our body.

Explanation:

From the mother cell it will be a differentiation, from the mother cell to be a mother cell hematopoietic, this will turn into a lymphatic mother cell until it will be 3 different kinds of lymphocytes, the B, T and NK.

Lymphocyte B is the responsible for the inmune system based in antibodies and antigens, due to specific proteins.

Lymphocytes T, are the ones that come from the mother cell of the bone marrow. They are the responsible for the immunity against some illness like cancer.

Lymphocytes NK (natural killer) are the responsible for killing bad cells (like cancer cells) because they "eat" them in a phagocytosis process.

As temperatures increase, gases such as CO2 diffuse faster. As a result, plant leaves will lose CO2 at a faster rate than normal

3241004551 [841]

Answer:

See the answer below

Explanation:

If the amount of light reaching a leaf and the water supply is adequate in the face of inadequate carbon dioxide, the latter becomes a limiting reagent in the process of photosynthesis.

The process of photosynthesis has two steps

1. The light reaction

2. The light-independent reaction/the Calvin cycle

Carbon dioxide is only required in the second step which is the Calvin cycle. This means that the light reaction proceeds at a normal rate but the Calvin cycle is slowed due to inadequate carbon dioxide. Overall, the rate of photosynthesis becomes limited to the amount of carbon dioxide that is available in the leaf.

Cómo comienza a formarse la materia más sencilla en el comienzo del big bag?

Andreas93 [3]

Answer:

Según el CERN, en los primeros instantes del Big Bang no había demasiado calor como para que se formen átomos, como el hidrógeno (el elemento más abundante del universo). En estos primeros instantes, mucho antes que se cumpla un segundo (10 a la menos 32), solo había quarks y fotones.

A plant leaf is an organism that traps light energy to make food. In what way does an animal stomach similar to a plant leaf?

Can exoskeletons break?

Harman [31]

If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around. They are not strong enough to hold organs or hold its shape.
